FAQ

What is the maximum operating frequency of the R5F10A6ELSP#G5?

The R5F10A6ELSP#G5 operates at up to 24 MHz using its on-chip oscillator or an external crystal up to 20 MHz. When using the high-speed on-chip oscillator (HOCO), the device achieves full performance at 24 MHz with ±1% accuracy over temperature and voltage. This frequency supports real-time LIN frame processing and ADC sampling without external clocking components. The R5F10A6ELSP#G5 maintains timing compliance across its full −40°C to +85°C operating range.

Does the R5F10A6ELSP#G5 support in-circuit debugging?

Yes, the R5F10A6ELSP#G5 supports single-wire debug (SWD) via the P00 pin (SWDIO) and the RESET pin (SWCLK), enabling full in-circuit programming, breakpoint setting, and real-time variable monitoring without dedicated debug headers. This capability is built into the on-chip debug circuitry and requires only a Renesas E2 or E2 Lite emulator. The R5F10A6ELSP#G5 does not require additional pins or external debug adapters beyond standard SWD connections.

What LIN protocol versions does the R5F10A6ELSP#G5 support?

The R5F10A6ELSP#G5 implements a hardware LIN controller compliant with LIN specification versions 2.0, 2.1, and 2.2, including support for automatic baud rate detection, sync field filtering, checksum calculation (classic and enhanced), and error handling (e.g., checksum, identifier, and bit errors). It does not support LIN 2.2A or later extensions such as secure boot or authentication. The R5F10A6ELSP#G5's LIN peripheral operates independently of the CPU core, reducing software overhead in LIN slave implementations.

Can the R5F10A6ELSP#G5 operate from a 3.3 V supply?

Yes, the R5F10A6ELSP#G5 supports a supply voltage range of 2.5 V to 5.5 V, making it fully compatible with standard 3.3 V systems. At 3.3 V, it delivers guaranteed performance up to 16 MHz and retains full functionality of all peripherals, including the LIN interface, ADC, and timers. The internal voltage regulator stabilizes analog blocks, ensuring consistent ADC accuracy and LIN PHY operation across the entire voltage range. The R5F10A6ELSP#G5 is commonly deployed in 3.3 V automotive sub-modules and industrial sensors.

Is the R5F10A6ELSP#G5 qualified for automotive applications?

Yes, the R5F10A6ELSP#G5 is manufactured and tested to Renesas' "Standard" quality grade, which explicitly includes automotive applications such as body electronics, lighting, and HVAC controls. It meets AEC-Q100 stress test requirements for temperature cycling, humidity, and ESD (±8 kV HBM), and is rated for −40°C to +85°C operation. While not designated as "High Quality" for safety-critical systems like airbags or braking, the R5F10A6ELSP#G5 is widely used in production automotive ECUs where functional safety is managed at the system level. The R5F10A6ELSP#G5 carries full automotive traceability and lot documentation.
